Being able to rotate everything a full 360 degree's

And yet some buildings do have more than two views. One of the zenith city buildings, I think it's the apartment, has two sides at one angle and two other sides on the opposite. Some fences rotate completely also.
And then there is the Krustyland shuttle that won't rotate at all.
There are some buildings that we have seen the back of, Moe's and King Toot's for example, in the show.
